IMPROVED CANAL-SCRAPEP..

Specification forming part of Letters Patent N0. 46, I 2S, dated January 31, 1865.

To all whom it may concern:

Be it known that I, THoMAs MILLER, of Columbus, Franklin county, Ohio, have invented a new and Improved Scraper for Olean- I'ng Canals and other Tater-Courses; and I do hereby declare that the following is a i'ull and exact description thereof, reference being had to the accompanying' drawings, and to the letters ot' reference marked thereon.

The nature of my invention consists in providin g a scraper movable about a pivot, so that an angle ot' any desirable Obliquity can be presented to the current by the person op erating the machine, by means of which obliquity the scraper can be guided to any part ot the channel to tear up and loosen the vegetable growth or sedimentaryT deposit, and allow the same to be washed off by the current.

A person of ordinary skill will be enabled to make and use my invention from the following description of its construction and ope1 ation.

Figure lis a plan 5 Fig. 2, aside elevation; Fig. 3, a front elevation, and Fig. 4 a view of the machine in operation.

The letters are the same in the various drawings.

A is a substantial scraper attached to the tongue by the bolts atb b. and having the parallels c c connected, as shown in the drawings. The parallels project behind the scraper, and the operator, who stands upon the footboard d, varies the direction ofthe scraper by throwing his weight upon one or the other of these parallels, thereby causing the scraper to assume an oblique angle with the direction of the draft, whereby the scraper is thrown to the right or left of the channel as the case may be.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination and arrangement ot' the tongue with projecting foot-board and parallels, whereby the movable principleis attained for the scraper, subject to the control of the operator, substantially as set forth, and for the purposes specified.
